Delta-T or delta temperature, seen in hardware reviews and cooling performance tests always stands for the value that you get when you subtract the ambient temperature from the measured temperature. velocity does not make sense without further explanation, cf. Main content. The basic formula is A - B/A x100. A delta E* value of 0.00 means the color of the sample is identical to the color of the standard. In other cases, it refers to the rate of change, such as in a derivative. Q represents the heat added, c is the specific heat of the substance, m is the mass of the sample, and Δt (delta t) is the change in temperature.
